Put the following steps of Meiosis in the correct order:
I. The cell divides into 2 daughter cells
II. Homologous chromosomes pair up in the center of the cell
III. Spindle fibers separate homologous chromosomes
IV. Chromosomes become shorter and thicker
A. I, II, III, IV
B. IV, III, II, I
C. II, III, I, IV
D. IV, II, III, I
What is Meiosis
Meiosis (listen); from Ancient Greek'lessening', since it is a reductional division) is a special type of cell division of germ cells in reproducing organisms that produce the gametes, such as sperm or egg cells. It involves two rounds of division that ultimately result in four cells with only one copy of each chromosome (haploid). Additionally, before the division, genetic material from the paternal and maternal copies of each chromosome is crossed over, creating new combinations of code on each chromosome. Later on, during fertilization, the haploid cells produced by meiosis between a male and female will fuse to create a cell with two copies of each chromosome again, the zygote.
Errors in meiosis resulting in aneuploidy (an abnormal number of chromosomes) are the leading known cause of miscarriage and the most frequent genetic cause of developmental disabilities.

Biological organization extends beyond the organism. Which group of terms would be included beyond organism in the same list
Answer:
This question lacks options, the options are:
A. populations, communities, and ecosystems
B. DNA, RNA, and protein
C. Cells, tissues, and organs
The answer is A
Explanation:
The biological level of organization shows the organized build up of life from cellular level to organismal level. However, this organization goes beyond the organismal level. Individual species of organisms can assemble to form a POPULATION.
Likewise, populations of different species can coexist to form a COMMUNITY. The community of organisms can interact with their abiotic environment to form an ECOSYSTEM.
Therefore, the level of biological organization extends as follows:
populations → communities → ecosystems

Answer:
They regulate some aspects of production and distribution
Explanation:
Got it Correct
In a mixed market economy, government agencies regulate some aspects of production and distribution. Hence option C is correct.
What is a mixed market economy?A mixed market economy is an economic system that combines elements of a free market system with elements of government intervention and regulation.
In a mixed market economy, goods and services are produced primarily by private individuals and businesses operating in a market environment. However, the government also regulates and oversees economic activity, and may provide goods and services directly to the public.
In a mixed market economy, the government's role is typically focused on providing public goods and services, protecting consumers, and maintaining competition.
This may include regulating some aspects of production and distribution, and ensuring that businesses operate in a fair and ethical manner. At the same time, individuals and businesses are generally free to pursue their own economic interests and to compete in the market on a level playing field.
Hence option C, they regulate some aspects of production and distribution is correct.

During transcription, RNA polymerase synthesizes RNA from a DNA template with the help of accessory proteins.
a. True
b. False
Answer:
The correct answer is a. True
Explanation:
The information to produce a protein is coded in the cells in deoxyribonucleic acid (DNA). Transcription is the process in which a DNA sequence is copied into a ribonucleic acid (RNA) sequence. This RNA sequence is a messenger RNA (mRNA) because it will be then translated into a functional protein. For this, the DNA sequence is read and an RNA strand is synthesized by an RNA polymerase (an enzyme that synthesizes RNA molecules from a DNA template). During the process participate other proteins, such as DNA binding proteins, activators, coactivators, etc. (accessory proteins).

how do the decisons that we make each day influence how efficiently our body operates
Answer:
Our decisions have direct impact on the operations or actions of our body.
Explanation:
The decisions that we make each day greatly influence our body and efficiently our body operates because the activities we do in daily life put pressure on our body system. If our decisions force us to do hard work so it makes our body more stronger and healthier as compared to those decisions which requires no hard work so our body is not strong enough and our body can't operates efficiently.
A biologist discovered a new animal. Upon studying its embryonic development, she observed radial cleavage with the blastopore developing into an anus. This animal was categorized as a parazoan. pseudocoelomate. deuterostome. protostome. radiata.
Answer:
The correct answer is ''deuterostome''.
Explanation:
Deuterostomes are a superphylum of animals in which the anus is formed in or near the blastopore area in the developing embryo, and the mouth is secondarily formed elsewhere. The oral apparatus that these adult animals enjoy does not come from the embryo's blastopore. Instead it is a new formation. They enter the Bilateria classification, where species that enjoy bilateral symmetry are incorporated. In deuterostomes, the primary phases of division occur in parallel to the axis between the tips. That is, the segmentation they have is radial when the embryo is in state 1 with four cells.

Given the range of current speeds shown on the graph above, would deposition ever be possible for clay (0.001 mm) or silt (0.01mm) particles?
Answer yes or no and explain your answer.
Answer:
Yes.
Explanation:
Yes, deposition can be possible for clay (0.001 mm) and silt (0.01mm) particles when the agent that carry its load is absent in that region such as wind. Wind is the agent that moves clay and silt particles with it so if there is high wind in a specific region, no deposition will occur while on the other hand, those areas where wind is not present, deposition will definitely occurs so we can say that deposition depends on the presence and absence of wind.
Which purpose is the main function of the light-dependent reactions of photosynthesis?
Answer:
The overall purpose of the light-dependent reactions is to convert light energy into chemical energy. This chemical energy will be used by the Calvin cycle to fuel the assembly of sugar molecules. The light-dependent reactions begin in a grouping of pigment molecules and proteins called a photosystem.
The light-dependent reactions convert light energy into chemical energy. The goal of the light-dependent reactions of photosynthesis is to collect energy from the sun and break down water molecules to produce ATP and NADPH. These two energy-storing molecules are then used in the light-independent reactions.
Indicate whether each statement is true or false: 1. Compliance is the tendency for blood vessel volume to increase as blood pressure decreases. True 2. Blood vessels with a large compliance exhibit a small increase in volume when the pressure increases a small amount. True 3. Venous compliance is approximately 24X greater than arterial compliance, so as venous pressure increases the volume of veins greatly increases. True
Answer:
1. False
2. False
3. True
Explanation:
1. Compliance is the capacity of a container to increase in size to allow it hold more content. Blood vessel, arteries and veins expand (increase in volume) to be able to accommodate a surge in blood flow, which is as a result of an increase in pressure of the blood from the heart pumping of the blood
Therefore, compliance in the tendency for blood vessel volume to increase as the blood pressure increases not decrease
The statement is false
2. A large compliance is indicative of being highly sensitive to changes in pressure
Compliance, C = ΔV/ΔP
From the above equation, a blood vessel with a large compliance, exhibit a large increase in volume when the increase in pressure is small
Therefore, the statement 'Blood vessels with a large compliance exhibit a small increase in volume when pressure increases a small amount; is false
3. The compliance of the vein ranges from 10 to 20 times (30 times in some literature) greater than arteries. A factor which can be affected by the vascular smooth muscle contraction or relaxation
Therefore, the statement, 'venous compliance is approximately 24 times larger than arterial compliance, so as venous pressure increases the volume of veins greatly increases' is true

Explanation:
Hydrocarbons are burned to produce water and carbon dioxide. Propane (C3H8) is a homologous series alkane that belongs to the hydrocarbon family. As a result, when propane is burned, three molecules of carbon dioxide and four molecules of water are produced.
Because there is an overabundance of oxygen, carbon dioxide is created when butane is completely burned.
